Well at last someone who explained how to do this in a simple way, I've spent all week looking at other videos on KZfaq and they all get bogged down in science and getting nowhere fast. I have the latest version installed now and at least I now know how to do it next time around. 73 and thank you.

A friend just got one of these and I am interested in them too, so I am letting you know we are watching and appreciate the information on this new piece of test gear, and new thing to discover and learn about. Cause it's fun too.

Nice video. Thanks. Note that while I was preparing to do this upgrade the naming and organization of the files on the Google drive changed around somewhat. But this video certainly helped me start out in the right direction. Again, thanks.

Thank you very much for the files and the link to your Google Drive! My NanoVNA does not specifically say it's the -H model. So, I loaded the non -H file. I got a display, but no trace and the thumbwheel was unresponsive. I thought I had bricked it. I went ahead and loaded the -H and it came back to life. Yay! I like having the battery icon. I read there is a diode to install to make it functional. More Google searching! :) Thanks again for the files!

Thanks for that Imsai, very useful i downloaded the lot ;)

Thank you so much for sharing. Best regards from Colombia.

If I do the upgrade, what structure map applies? They seem to change with upgrades.

The board is running an embedded Real-Time Operating System (RTOS) called ChibiOS. It's open source (see www.chibios.org/ for more info) and targets a number of different embedded microcontrollers, including the ST Micro ARM Cortex chips. The CLI you see is based on a stubbed UI that ChibiOS provides and the "info" command is telling you more about the build environment for ChibiOS rather than the application that's linked with it. So maybe you can only really rely on the build time in there as a version identifier, as the rest has more to do with how the RTOS was configured when it was built.

How to update firmware nanovna by andoir nanovna sir??

HI, is there a special cable to be used? Still trying cables and havent had luck yet with DfuSe finding the device. Hopefully I can come delete this question. lol. thx

Those of you all reading this circa May 2022, recommend you join the NanoVNA group. The whole process has changed and become more streamlined with a new app that is a combination tool to process the measurements and data as well as enter the consoles commands. Links to the latest DFU firmware files as well as tutorials and NanoVNA documentation can be found in the files section and there is a wiki as well.

tnx for sharing thumbs up!!

hi and thanks for the video. i had to stop as the files are no longer on the drive, unless i am looking in the wrong spot. thanks

How do i find what my current firmware version is?

Great ty, but i have all istall device regognize and when i choose file .dfu, i have a message ( THIS FILE IS DOESN'T HAVE A CORRECT FORMAT ty

literally could have cut out the first 4 minutes of this video. Just walk us through the bloody procedure. Thanks! 73

Please drop the pronouns and state the names of things. It would be followable.

I goto the Google drive folder, and there are 5-8 files that MAYBE might be the right ones for my VNA - but have absolutely NO idea which, if any of these are correct!!! I have the brand new 2022 VNA-H model. This is like wallowing around in a pool full of beans, without Ann Margeret! :)
